Introdução

Follow the steps in this guide to replace the Home Button Assembly, including the gasket and cable, in your iPad Air 2 LTE. Note that home buttons are paired with their respective logic board, so Touch ID will no longer work after you replace the Home Button Assembly.

Parts of this guide were shot with a Wi-Fi model and as such the internals may look slightly different from the LTE model. The procedure is the same for both models except where noted.

Step 1 iOpener Heating

We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.

Place the iOpener in the center of the microwave.

Place the iOpener in the center of the microwave.
For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it may overheat and burn.

Step 2

Heat the iOpener for thirty seconds.

Heat the iOpener for thirty seconds.
Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.
Be careful not to overheat the iOpener during the repair. Overheating may cause the iOpener to burst.
Never touch the iOpener if it appears swollen.
If the iOpener is still too hot in the middle to touch, continue using it while waiting for it to cool down some more before reheating. A properly heated iOpener should stay warm for up to 10 minutes.

Step 3

Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.

Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.
The iOpener will be very hot, so be careful when handling it. Use an oven mitt if necessary.

Step 4 iPad Air 2 Wi-Fi Opening Procedure

If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.

Lay overlapping strips of clear packing tape over the iPad's display until the whole face is covered.

This will keep glass shards contained and provide structural integrity when prying and lifting the display.

This will keep glass shards contained and provide structural integrity when prying and lifting the display.
Do your best to follow the rest of the guide as described. However, once the glass is broken, it will likely continue to crack as you work, and you may need to use a metal prying tool to scoop the glass out.
Wear safety glasses to protect your eyes, and be careful not to damage the LCD screen.

Step 5

The following steps involve using an iOpener to soften the adhesive holding the front panel assembly in place. When using the iOpener, be sure to heat it in the microwave for no more than 30 seconds.

The following steps involve using an iOpener to soften the adhesive holding the front panel assembly in place. When using the iOpener, be sure to heat it in the microwave for no more than 30 seconds.
Handling it by the tabs on either end, place a heated iOpener over the top edge of the iPad.
Let the iOpener sit on the iPad for two minutes to soften the adhesive securing the front panel to the rest of the iPad.

Step 6

While the iPad looks uniform from the outside, there are delicate components under certain portions of the front glass. To avoid damage, only heat and pry in the areas described in each step.

As you follow the directions, take special care to avoid prying in the following areas:

Step 7

Place a suction cup over the iPad's front-facing camera and press down to create a seal.

To get the most leverage, place the suction cup as close to the edge as possible without going past the edge of the display.

Step 8

Firmly pull up on the suction cup to to create a small gap between the front panel and the rear case.

Do not pull too hard or you may shatter the glass.

Once you've opened a sufficient gap, insert an opening pick into the gap to prevent the adhesive from resealing.

Step 9

Slide the pick along the edge of the display, towards the headphone jack.

If there is still a considerable amount of resistance when sliding the opening pick, repeat the iOpener heating procedure and apply additional heat.

Be careful not to let the opening pick slide between the fused LCD and front panel, as doing so can permanently damage the display.
